BMW 325XI Manuel D’Utilisation

Initializing is necessary to familiarize the 
system with the correct inflation pres-
sure.

Repeat this process after any changes 
in tire inflation pressure, tire rotation or 
replacement. Do not carry out further 
system initialization after adjusting the 
inflation pressure and letting the system 
"learn" the correct pressures.

1. Check the tire inflation pressures in 

all the tires, comparing them with the 
inflation pressure chart on page 

and adjusting their pressure if neces-
sary

2. Turn the ignition key to position 2

3. Press button as long as you need to 

until the indicator lamp in the instru-
ment cluster lights up. After a little 
while, the indicator lamp will go out 
by itself

4. After a few minutes' driving time, the 

Flat Tire Monitor adopts the current 
pressure levels as the reference, and 
from that point on, can detect and 
report a flat tire.

The Flat Tire Monitor automatically 
assumes operation whenever you turn 
the ignition key to position 2. Unless 
manually deactivated, it is always on 
during normal vehicle operation.

To deactivate the system: press the 
button, the yellow indicator lamp comes 
on.

To activate the system: press the but-
ton again, the indicator lamp goes out.

You should deactivate the system 
before driving with snow chains, as the 
chains can generate spurious warnings 
and/or prevent the system from detect-
ing actual pressure loss.
